Application filed January 27, 1913. Serial No. 744,443.

To all whom it may concern:

Be it known that I, CLARENCE H. HAP- ooon, a citizen of the United States, residing at Toledo, county of Lucas, and State of 'Ohio, have invented certain new and use-' ful Improvements in Weighing-Scales, of which the following is a specification.

In the accompanying drawings I have shown my invention as applied to a computing scale of the pendulum type with a drum chart or price indicator, but it will be understood that it is applicable to other forms of scale with or without modification; and though the precise form of the invention disclosed is that preferred by me, it is shown and described for the purpose of illustration only, and my invention is capable of many modifications in respect thereto all coming within the scope of the following claims which are intended to distinguish my invention from what is old in the art, without, however, abandoning or dedicating to the public any part thereof.

Referring to the accompanying drawings forming part of this application, Figure 1 is a side elevation partly in section of a pendulum scale with a computing cylinder, embodying my invention; Fig. 2 a front elevation thereof; Fig. 3 a rear elevation partly in section on the vertical plane of the line 33 of Fig. 1; Figs-4 and 5 side and front elevations respectively of a detail to be described later; Fig. 6 an enlarged transverse section on the line 6-6 of Fig. 2; Fig. 7 an enlarged side elevation of the connecting member between the scale beam and the computing chart cylinder; Fig. 8 a fragmentary view of the upper end of the same at right angles to the plane of Fig. 7; Fig. 9 a similar view of the lower end of the connection; F i s. 10 and 11 perspectives of certain detai s to be described later; Figs. 12 and 13 fragmentary side elevations from opposite sides of an improved check link connection forming part of my invention; Fig. 14: a plan view partly in section of the same; Fig. 15an end view thereof; Fig. 16 a detail in perspective; Fig. 17 is an elevation on the plane of Fig. 3 of the connection between the beam and the pendulum structure shown in said figure; Fig. 18 is an elevation of the same parts taken at) right angles to the plane of Fig. 17; Fig. 19 is a fragmentary section of the end of the beam showing the mounting of the knife edge pivot; Fig. 20

is a side elevation and Fig. 21 a perspective of the knife edge detached; Figs. 22 and 23 are elevations and longitudinal sections respectively of the agate for cooperating with said knife edge and its immediate support.

Referring now particularly to Figs. 1, 2, 3, I will first describe briefly the more prominent features and elements of the scale to which my invention has been applied. Upon the scale base 18 at one end thereof, is mounted a fulcrum horn 19 which carries the scale lever 20, and at the other a housing 21 which contains the automatic load counterbalancing mechanism and is surmounted by a-cylindrical casing 22' contain.- ing the cylindrical computing chart. Upon the beam 20 is mounted. the usual platform 23 for receiving the material to be weighed nected by a stirrup 31, strap 32 and segment 33 with a pendulum load off-setting means 34. The stirrup 31 isof novel construction comprising a socket member 106 which is longitudinally. bored at 107 to form a socket for the shank 108 of an agate supporting member 109. The upper end of the socket 107 is reduced and tapped at 110 to receive the correspondingly reduced and threaded upper end of the shank 108 and the lower end of the socket member is split at 111 and formed with laterally projecting ears 112112 which receive screws 113--113 to clamp or draw the members of the socket around the shank 108. By this means it will be seen that the effective length of the member 31 may be adjusted as desired. The shank 108 is provided with a milled head 11 1 for manipulating the same and the agate supporting frame 109 is swiveled thereto by the headed bolt or rivet 115. The frame 109 is struck up out of sheet metal and comprises the legs or branches 116-116 and an intermediate wide portion 117 through which the supporting pivot 115 extends, and the lower ends of the branches 116116 are inwardly turned as at 117-117 to support a U-shaped plate or trough 118 which receives the agate, the ends of said trough abutting against the side members or legs of the frame. The bottom 119 of the trough is formed with a transverse corrugation or rib 120 upon which rests the agate 121 so that the latter is capable of a limited tilting movement but is prevented from lateral movements by the sides of the trough and from extended longitudinal movement by the legs of the frame. The upper edges of the trough are inwardly bent as seen at 122122 in Fig. 23 to retain the agate against vertical movement.

The nose or end 123 of the scale beam is perforated as at 124 (see Fig. 20) and formed with a cross groove 125in register with the perforation to receive a knife edged pivot 126 which is tapped at the back (see 127, Figs.- 21 and 22) to receive the end of a screw 128 extending through the perforation in the beam end and securingthe knife edge thereto. The knife is chamfered or cut away at its opposite ends 129-129 so that any end contact that it may have with the frame 109 will be only at the extreme edge of the knife and will not therefore furnish much friction. The cotter pin 130 provided with a knurled head 131 extends between the legs of the frame 109 above the beam end to prevent the knife edge leaving the agate. When it is desired to remove the stirrup from the beam it is necessary only to withdraw the cotter pin when the frame 109 furnishes ample space for the purpose. It will be readily seen that by this construction the agate is free to adjust itself to con form to the knife edge automatically and the parts are readily assembled and associated when required.

The load od-setting means is suspended by knife edges from brackets 36 within the housing, and is adjustable relatively to the segment which is pivoted at 34: thereon by set screws 85-35 tapped into the pendulum head and bearing against the edge of the segment. The scale lever or beam is also formed with a laterally extending arm 37 to which is attached by means to be described more in detail later a connecting rod 38 which carries'a rack 89 for turning the cylinder chart 40 through the medium of the pinion n upon the arbor or shaft thereof. The rod 38 above referred to extends through a hollow column 42 of which there are two shown connecting the housing with the chart casing, and the latter rests upon a casting d3 supported by brackets 4H4 extending upwardly from the hous- The cylinder or drum shaft extends through openings 45' formed in the ends of the casing and rests upon anti-friction disks it-46 pivoted in brackets 47%? upon the exterior of the casing the whole being covered by end plates 458-48 secured to the casing. From the brackets 47%? extend additional brackets lQ-tl which are bent inintense wardly over the ends of the cylinder shafi and carry screws 5050 which are adjusted to prevent vertical displacement of the shaft. Other screws 5151 extending through the brackets in a horizontal direction serve to prevent endwise movement of the shaft. As shown in Fig. 1, the casing is provided with front and rear side openings 5253 for inspection and readingof the chart by the operator and the purchaser respectively.

The invention which forms the subject matter of the claims of this application will now be described in connection with the scale briefly set forth in the foregoing paragraphs. In order to secure a connection between the rotary chart and scale beam which shall be as nearly frictionless as possible, and therefore not interfere with the accuracy of the reading of the scale, T have perfected a novel construction of rack rod for meshing with the pinion of the former, the novelty relating in part to the form of connection between the rod and the lever. At its lower end the rack rod 38 is screwed into a split sleeve 54 by which it is tightly secured, and a lit-shaped leaf spring is clamped between the lower end of said sleeve and a nut 56 screwed upon the projecting end-of the threaded rod, the other end of the leaf spring being clamped between a casting 59 and a sheet metal plate 60 secured to the casting by screws 60'60, and forming part of the means by which the casting is connected to the leveryas will be now described. (See Figs. (11 inclusive). The lateral arm 87 of the lever above referred to is formed with bosses or projections 6l-61 to which is secured by screws 6262 a plate 83 (see Figs. 9 and 11) which is shouldered near its ends at 64-45%, and formed into up wardly directed knife edges 65-65. The under edge of the plate 63 is cut away at its middle 66 and formed with a downwardly directed knife edge 67. The plate 60,-de scribed above as attached to the lower face of the casting 59, engages the knife plate 63 to formthe' pivotal connection between the rack rod and the lever, being bent downward at its opposite ends 68--68 and formed with recesses 69-69 to receive the upwardly directed knife edges 85-65 and form seats for the same. Midway its length the plate 60 is also provided with a laterally extending tongue 70 which is bent downwardly at Y1, then forwardly under the body of the plate 60 as at 72, and tapped at 73 to receive a screw 74 for co-acting with the downwardly directed central knife edge upon the knife plate 63. Upon the screw ust referred to is threaded a set nut 75 by which the screw, after it is adjusted to barely clear theknife edge, is lbcked in position. The weight of the connecting rod and its associated parts normally rests through the medium of the plate spring 55 and hearing plate 60 uponthe upwardly directed knife edges, but in case of a sudden downward movement of the lever or upward movement of the rack rod, the screw 74: will bear upon the downwardly directed knife edge 67 and prevent displacement of the parts but without interfering at all with the relative rotation of the parts, it being observed that the terminal and intermediate knife edges are in the same horizontal line.

At its upper end the rack rod 38 is shouldered as at 76 and a strap 7 7 secured thereto which at its u per end 7 8 is bent laterally and perforate to receive a threaded shanlc 79 of a rack 80. The latter depends from the end 7 8 of the strap and is loosely held thereto by a conical nut 81, the opening in the strap being sufliciently large to allow some play or lateral movement of the shank 79. A look nut 82 is also screwed upon the shank 79 for. its common purpose. It will thus be seen that the rack depends from the upper end of the strip 77 and is free to move with relation thereto, though its sidewise movement is limited by pins 8S83 projecting from the strap 77 (see Fig. 8). By reason of this suspension of the rack with the limited play, any binding. between the rack and the pinion which might be caused by a slight displacement of either one or the other from its correct position is avoided, since the rack is free to yield and accommodate itself to the pinion, and yet tends to return to its proper position.

The casting 59 above referred to, as secured to the lower end of the rackrod by the leaf spring, is overweighted on the toothed side of the rack as at 84, in order to hold he rack yieldingly in engagement with its pinion. By the construction above described I practically eliminate all the friction in the connection between the scale beam and the cylinder chart and therefor get rid of any error or inaccuracy from this source.

Turning now to Figs. 1 and 13 to 17 inclusive, I will describe the improved form of check link by' which I reduce the friction commonly found in this part of scales. The lower ends of a stationary post 27 and check rod are normally at about the same level and to the lower end of each is screwed or otherwise fastened a knife plate 85 which is generally rectangular in section but pro-- vided at diagonally opposite corners with parallel ears 86-86 which are formed with oppositely directed knife edges 87-88.. The knife edges 87--87 upon one side of the pair of posts are directed toward each other and those 88-88 upon the opposite side are directed away from each other. A. thrust member 89 having open end seats 90--9O extends between the knife edges 8'?-87, and a tension member 91 having eyes 92-92 embraces the knife edges SSS-88 so that a movement of the posts toward each other is checked by the thrust bar 89, and a move-- ment away from each other prevented by the tension bar 91. The two bars or members of the link; are held and pivoted together by a screw bolt 93 provided with a nut 94 and spaced apart by a sleeve 95 surrounding said bolt. With a check device constructed as above described, the members are free to move with respect to each other and any slight twist or lateral displacement with reference to each other has no material effect upon the friction between the parts.

Turning now to Figs. 1, 2, 4:, 5, and 6, I will describe a device shown therein for conveniently indicating the prices of various commodities in convenient relation to the computing chart. Immediately in front of and below the horizontal sight opening upon the salesmans side of the chart casmg, I mount a horizontal rod 96 supported in cars 97-97 projecting from the casing and u on which a small casting or castings 98 see Fig. 6) are free to he moved longitudinally of the rod and set in any desired position by a set screw 99. The casting carries an upwardly projecting car 100 upon which is mounted a pointer 101 which may be brought into registry with any of the price indications 102 upon the lower edge of the sight opening. At its lower end the casting 95 98 is formed with an eye 103 for the reception of the hook 104- of a. tag 105 bearing the name of any commodity which is designed to be sold with the aid of the scale inquestion. Each of these tags, which are. best shown in 100 Fig. 5 of the drawings, is provided at its lower edge with an opening into which may be inserted the hook of another tag so that any desired number of tags bearing the names of diderent commodities may be sus- 105 pended from a single slide or casting. .Obviously any number of these slides 98 may be used, though in Fig. 2 of the drawings I have shown but two of them. In case the operator or salesman. is forgetful or uninformed as to the prices of various commodities and especially in the case of commodities whose prices fluctuate from day to day, the tags suspended from the several slides which are properly positioned according to the price of the commodity form an eilicient means of refreshing the memory of the salesman.
